Phelps became the most decorated Olympic athlete earlier last Tuesday when he won his 19th medal overall -- besting a record previously set by Soviet gymnast Larisa Latynina. He received a Tweet and congratulatory call from none other than President Barack Obama, who called him "the greatest Olympian ever."

"Once I hang my suit up I want to be able to look back and say I've done everything I can in my career -- whether that's having fifty gold medals or having sixteen total medals," the Baltimore, Maryland native has told Us Weekly last week. "If I can say I've done everything I've wanted, I think that's really all that matters."
